formt-ends to prevent the slivers rising between the disks, and causes them to work down till they find a free place to move in. By moving the bar R, to the right or left, so as togive theguide plates G, G, a greater or `less inclination, the tendency of the sliver to rise is increased or diminished, and the con-` densation regulated.` From the condensing disks, the slivers pass on to the spool F, which rests upon the spool drum E, but is providedwith journals which work in vertical guides g, g, on the framing. The spool l receives motion by friction from the drum E, which receives rotary motion through a` bandH, from the doffer, and a traversing motion througha toothed wheel W, on the shaft, gearing with an oblique toothed wheel on a stud secured to one side of the framing. As the spool receives the slivers, it

keeps rising, and its journals keep working up in the guides g, g, until they leave the ,Xedpart of the said guides and come in contact with the upper part of two levers 72 7L, which form movable continuations of the front parts` of the saidguides. These levers are hung loosely upon the shaft of the drum E, and have a bar N, attached to their lower ends, whose, weight tends to keep them in an upright position, as shown in black outline in Figs. l and 4. The upper ends o one h', of the levers, while the spool is in its place above the drum E, is secured by a catch I, but as soon as the sliver on the spool increases to such a diameter, as to raise the journals of the spool W, high enough to lift thecatoh I, the levers are left free, andthe spool is then caused to roll down the drum E, by the motion of the latter, until it balances the bar N, as shown in dotted outline in Fig. l, when an empty spool is dropped into the fixed or lower part of the guides g, g. The revolution of the empty spool' with the drum E, atonce commences, and the full spool is then raised by hand and held over the empty one, around which the slivers will soon lap, and then the full one may be taken away without disturbing the slivers or making any waste whatever.

lVhat I claim as my invention, and desire to secure by Letters Patent, is

l. The combination of the several parts herein before described for conducting and condensing the fibrous material from the doffer of a carding engine to the spool, to wit.

2. The two sectional rolls working in coned upon shafts in front of and parallel toY the said rolls, with the guide plates to govern the position of the slivers between the said disks, for twisting and condensing the slivers as they are conducted from the doer to the spool, substantially as herein set forth. el. The manner of constructing the upper part of the guides g, g, of the journals of the spool F, to wit z-making the outside portion thereof form parts of levers L, it", whose operation is controlled by a bar or weight N, and a catch I, substantially in the manner herein described, for the purpose set forth.
